Selena was comparing the flying seeds of different birds in science class.
Which of the three words why faster why?
Select the correct response
1. the blue jay Five Spices because it's rate is 20 m/s
2. the Cardinal flies fast is because it's right is 10 m/s
3. The robin Place passes because it's rate is 15 m/s
4.they all fly at a rate of 10 m/s
____________________________
The slope, in this case, expresses the variation of the distance with respect to time (that is, the speed).
Comparing the slopes
Blue Jay's Flight
slope 10 m/s
__________________
Robin's Flight
slope = (y1-y2)/ (x1-x2)
Selecting the points (x, y)
Point 1 (2, 30)
Point 2 (6, 90)
slope = (90- 30) m / (6-2 )s
=(60)/ 4
= 15 m/s
